12 week scan tomorrow and they didn't tell me to drink lots of water?

When I had a scan to investigate for PCOS I was told to drink a whole load of water before the ultrasound but there was no mention of it in the letter about my 12 week scan. Do I have to? Scan is at 8.30 am and I find it hard enough to get half a glass down me at that time, never mind a litre or whatever.

no - depends on how sophisticated the machines are, the more old fashioned ones need you to drink some water to push your bladder up so they can see more clearly. If they haven't told you to, it won't be necessary....good luck!

Even if they say a full bladder which mine still does, I never had to drink a glass of water, used the bathroom before I set out but not at the hospital which I would have done normally before going into an appt. A few sips of water has always seemed to be enough for the scans.

Hmm, it must vary from region to region. I just had my 12wk scan a couple of weeks ago and was told to drink a lot. I was murder as they pressed the scanner over it, but worth it as we had a great view (??) and the sonographer kept going on about my 'nice full bladder' and 'perfect textbook position of the baby'

BUT conversely, when we lived in Wales we got a 21wk scan and no 12 wk scan and I was told to have a full bladder and they couldn't get a clear enough picture cos you couldn't see the baby's head - it was literally stuck under my enlarged bladder! - I suggested I go for a pee (before I did it right there on the table) and 'miraculously' you could then see everything. The staff couldn't believe it, but I guess it was because it was at a bigger stage, it didn't need propping up.

I'm having my 12 week scan the week after next and they said they will be doing in internal scan rather than through the abdomen since it gives them a better picture (they'll also be measuring the nuchal fold).- anyone else had this for their 12 week scan?
